MacOS 10.8 or later and iOS 6.0 or later are now required, since
Xcode 6 can no longer build executables that work on older OSes.

Many, many Android improvements.

iOS: Fixed rotation to work with the new iOS 8+ API.

X11: pong is now playable.

5.34

24-Oct-2015

Fixed a crash when hot-swapping monitors while locked.

Fixed some incorrect output from xscreensaver-command -watch.

Various OSX and iOS performance improvements.

5.33

04-Jul-2015

New hacks, splitflap and romanboy.

Better detection of user activity on modern GNOME systems.

Sonar now does asynchronous host name resolution.

Improved Unicode support.

Updated webcollage for recent changes.

Various minor fixes.

5.32

18-Nov-2014

Fixed some X11 compilation problems.

Fixed display size and shake gestures on iOS.

OSX/iOS Performance improvements.

5.31

15-Nov-2014

New hacks, geodesicgears, binaryring and cityflow.

UTF-8 text support (instead of only Latin1) and antialiased text
on X11 with Xft (instead of only on OSX/iOS) in fontglide,
noseguy, fliptext, starwars, and winduprobot.
The other text-displaying hacks (apple2, phosphor, xmatrix,
and gltext) also now accept UTF-8 input, though they convert it
to Latin1 or ASCII.

glplanet now has both day and night maps, and a sharp terminator.

Fixed webcollage on OSX.

Fixed a transparency glitch in winduprobot.

lockward works on iOS.

Text and image loading work on OSX 10.10.

Rotation works properly on iOS 8.

Added a search field on iOS.

Preliminary, unfinished support for Android.

5.30

11-Sep-2014

New hack, winduprobot.

Many improvements to lament, including Leviathan.

Fixed the normals in flyingtoasters: shading is correct now.

Implemented TEXTURE_GEN in GLES: flying toast is now toasted on iOS.

Make cel-shading sort-of work in skytentacles on iOS.

Fixed dragging-to-rotate on rotated iOS devices, I think.

Dragging has inertia now.

Most hacks respond to mouse-clicks, double-taps and swipes as
meaning “do something different now”.

Reworked OpenGL fonts.

The OSX auto-update installer wasn't working. This time for sure?

Various minor fixes.

5.29

08-Jun-2014

Downgraded to Xcode 5.0.2 to make it possible to build savers
that will still run on 10.6 and 10.7. Sigh.

Backed out recent locale-related changes, since they broke far more
things than they fixed.

Fail gracefully with ridiculously small window sizes.

xflame and flag ignore bitmap option on MacOS.

speedmine prefs work on MacOS.

Better explosions in boxed.

More dynamic motion in sproingies.

More options in flipflop.

Minor updates to topblock.

Various other minor fixes.

5.00

23-May-2006

Ported to MacOS X! (10.4.0 or newer)

API change: instead of providing a single screenhack() function that
does not return, screen savers using the screenhack.h framework must
now provide “init” and “draw one frame” functions instead. All
bundled savers have been updated; third-party patches will need
work.

All image-loading happens asynchronously.

xscreensaver-getimage-file caches the contents of the image
directory for a few hours, so consecutive runs won't have to re-list
the whole directory tree.

New hacks, topblock and glschool.

Removed xteevee (superceded by xanalogtv).

Added variable-sized puzzle pieces to jigsaw.

Changes to the defaults and command-line options of many hacks to
make the .xml files more consistent.

Reap zombies in glslideshow and carousel.

sonar works without setuid on MacOS (dgram icmp).

xmatrix -mode pipe displays the text of a subprocess.

endgame has higher resolution chess-piece models.

webcollage takes a -directory option to get images from a local
directory.

The RPM spec file no longer auto-restarts xscreensaver when a new
version is installed. Restart it manually.

4.24

08-Feb-2006

New versions of cube21, glsnake, celtic.

Backed out a DPMS-related patch that cause desktop flickering with
some X servers.

Fixed startup crash in getgroups() when running setuid.

Default to not displaying stderr on the saver window.

Fixed bad free() in “Documentation” button.

Don't try to run hacks that aren't installed.

Minor fixes to various XML config files and man pages.

4.23

21-Oct-2005

New hacks, glhanoi, cube21, timetunnel, juggler3d, and
celtic.

New versions of tangram, webcollage, hypertorus, polytopes,
and ripples.

sonar is now quiet about unresolvable hosts.

Minor corrections to BASIC code in apple2.

xscreensaver-demo now provides an RPM clue when none of the hacks
seem to be installed.

Don't install ant by default, since there is some Java tool of
that name, which was causing confusion. And also it's boring.

Made screen grabbing work again on MacOS 10.4.2.

No longer prints bogus warnings about ClientMessages intended for
the window manager.

Ignore unprintable characters in passwd entry field.

Fixed yet another cross-host-display image-loading endian problem.

xscreensaver-command -watch and -time now work on 64-bit
machines.

4.22

22-Jun-2005

Fixed a bug in the new mouse-motion code that caused the screen to
never blank on multi-head non-Xinerama systems. Oops.

On Xinerama systems, xscreensaver now runs one hack on each monitor
(just like in “real” multi-head mode) instead of running one hack
stretching across all the screens. Note that for this to work with
any 3rd party screensavers, they must update their “vroot.h” file.

Fixed a bug that (sometimes) caused the window manager close box to
kill xscreensaver-demo with a crash instead of a graceful exit.

Updated xscreensaver.pam to the Red Hat 7.3 way.

More Gnome2-related configure crap.

Updated to latest config.guess and config.sub.

Fixed occasional core dump in distort.

Added a Linux fsck failure and kernel panic to bsod.

Added MacOS X kernel panic to bsod.

Fixed a bug in bsod (all bsod bugs are ironic.)

Fixed a bug that caused xscreensaver-gl-helper to print a nonsense
visual ID with some versions of printf: this could cause GL
programs to display incorrectly (e.g., flickery.)

4.05

11-Jun-2002

More configure tweaks to try and get things working on systems
that both Gtk 1.x and 2.x installed.

New hack, endgame.

Minor updates to gltext.

4.04

31-May-2002

Support for GTK 2.x / GNOME 2.x.

The configure script will now use pkg-config if you have it, in
preference to gtk-config, etc.

New hacks, lavalite, queens, and anemone.

Minor updates to spheremonics, gltext, xmatrix.

You can use the mouse to manually spin most of the GL hacks now
(when they are displaying in a window.)

Fixed a bug in webcollage (due to recent Alta Vista url changes)
that was causing it to try and load incorrect image URLs.

Made xscreensaver-getimage use gdk_pixbuf if it is available: this
means that those hacks that load images will no longer rely on “xv”,
“xloadimage”, etc. This will close a race condition that could
sometimes cause your desktop background to be changed; and also
makes it possible for those programs to operate on image files when
running in windowed mode.

webcollage can now be used in conjunction with driftnet to
display images snooped from your local ethernet instead of obtained
from search engines.

Fixed the gltext bug that sometimes caused horizontal lines to
vanish again. This time for sure.

Sped up webcollage by adding a C helper program to replace the PPM
pipeline. It also pastes images semi-transparently now.

Added support for the gdk_pixbuf library: if this lib is available,
then blitspin, xflame, and flag can load GIF, JPEG, and PNG
images in addition to XPM and XBM.

Fixed a rare race condition where the desktop-grabbing hacks could
sometimes leave the screen wedged, if the user moved the mouse
exactly when they were grabbing the screen image (it would un-wedge
the next time the saver timed out or was activated.)

Made SIGHUP restart the daemon process (though using
xscreensaver-command -restart is still the preferred way.)

Tweaks to xspirograph.

Minor configure and portability tweaks.

4.00

02-Jan-2002

Redesigned xscreensaver-demo GUI: it now includes small-preview
and per-hack configuration dialogs.

Added three new modes of operation: One Screen Saver, Blank
Screen, and Don't Blank (in addition to the historical Random
Screen Saver).

Configure now defaults to installing the hacks in
<prefix>/lib/xscreensaver/ instead of <prefix>/bin/. (Most distros
already did it this way.)

New GL hacks, menger, engine, flipscreen3d.

Made sierpinski3d be more colorful.

New versions of xmatrix and nerverot.

Fixed a bug in starwars that made the font be drawn with thin
lines in -root mode.

Fixed a bad colormap bug in crystal that could make subsequent
hacks malfunction!

Made gflux able to grab screen images (-mode grab).

Updated webcollage for recent search engine changes.

Removed most command-line options to xscreensaver: just edit the
~/.xscreensaver file instead.

Improved behavior on multi-screen and Xinerama systems: the mouse
now stays on the screen where the user left it, and the password and
splash dialogs always appear on the screen that has the mouse.

Made the splash dialog use more Gtk-like colors; made it have only
two buttons, “Settings” and “Help”.

Made sonar understand .ssh/known_hosts2 format files, and be
better about stripping out illegal addresses.

3.34

25-Oct-2001

Turned memoryLimit off by default, sigh. Apparently some versions
of the GL libraries (appear to) allocate hundreds of megs for every
GL program, so memoryLimit was causing GL programs to malfunction
or crash on those systems.

Improved fading on TrueColor XFree86 4.1.x systems.

New GL hack, circuit.

Added fuzz mode to decayscreen.

New version of whirlygig.

Added links to xplanet and sphereEversion.

Fixed rare race condition that could make sonar hang.

Fixed potential crash in speedmine.

Made xscreensaver-demo not crash when imageDirectory was set to a
non-existent directory.

Made xscreensaver-command -deactivate work when the saver is not
active: what that does is reset the idle timer, as if keyboard input
had been detected. This was added for the benefit of people writing
DVD-playing software: they can now prevent the screensaver from
kicking in by sending a -deactivate message once a minute while the
movie is playing and not paused.

Various minor portability tweaks.

3.33

03-Jun-2001

New hacks, speedmine and whirlygig.

Sped up pyro, made the explosions look a bit better.

Added better stars to glplanet and starwars.

Many internal changes to webcollage.

Some new options to attraction.

Minor fix to noseguy to avoid un-erased pixels.

Rewrote the screen-eraser effects so that they complete in the same
amount of time regardless of how slow your X server is (some of them
were glacial on servers with slow blitting.)

Fixed a potential free memory reference that could sometimes cause a
crash at startup.

Possibly fixed a problem that could cause the daemon to crash with
an X error. I was never able to reproduce this problem, but I think
I might have figured out what caused it.

Worked around a problem that caused PAM authentication to fail on
some Red Hat 7.x systems.

Added a memoryLimit parameter that controls the amount of memory a
graphics hack may allocate: if they try to allocate more than this,
malloc() will fail (and they will exit or (safely) crash, rather
than hogging memory.) Default is 50M.

Made gnome-help-browser be the default way to display man pages in
xscreensaver-demo, if running on a GNOME system.

3.32

16-Apr-2001

The image-manipulating hacks (slidescreen, etc.) can now operate
on randomly chosen image files from disk, or on frames captured from
the system's video input, instead of (or in addition to)
manipulating images of the desktop.

Rewrote vidwhacker to use the new image-grabbing mechanism.

Made fading work on TrueColor XFree86 4.x systems.

Fixed a subtle rendering bug in atlantis (the fish were inside
out!)

Made atlantis have a texture simulating light reflections from the
surface of the ocean.

Fixed up label placement in molecule.

Better color bars in xteevee.

Made install-strip not try to strip scripts.

3.31

29-Mar-2001

Put in more sensible defaults for DPMS, and updated the
documentation to reflect the fact that all your DPMS settings are
now belong to xscreensaver.

Fixed the xscreensaver.spec file so that --force is no longer
needed.

New versions of rotzoomer and nerverot.

Fixed an OSF/1 compilation problem in molecule.

3.30

19-Mar-2001

New hacks, molecule, dangerball, and rotzoomer.

New version of gflux.

Made gltext able to display the current time.

Fixed a floating-point-precision problem in gltext that sometimes
caused horizontal lines to vanish.

Removed the -window-id option from the hacks: it never worked
right, and was unnecessary.

Made the starwars hack use thicker lines, antialias the text, and
fade out at the far edge instead of just dropping off.

Fixed an SHM segment leak in moire.

3.29

13-Feb-2001

Better rendering of the new logo.

New hack, gltext.

Added -planetary option to gears, to draw a different kind of
gear system.

Made motion and rotation be smoother in gears, glplanet,
moebius, rubik, and sierpinski3d.

Improved coloration in sierpinski3d.

Made the GL hacks react to window size changes.

Made most of the GL hacks take a -fps option (like pulsar did), so
you can use them to benchmark your 3D hardware.

Fixed the previous fix to sonar.

Minor fix to nerverot. Made sonar able to ping hosts on DEC OSF1.

Eliminated a bogus “didn't get enough colors” warning in some of the
hacks.

3.28

02-Feb-2001

New logo for xscreensaver!

New hacks, starwars and stonerview.

Made the motion of the bouncing ball in stairs be a little less
jerky.

Made newly-added screenhacks be added to .xscreensaver
automatically: if there are hacks in the app-defaults file that are
not also in ~/.xscreensaver, they will be added to the end of the
list.

Redid the Screensaver Options part of the control panel;
xscreensaver now lets you configure your DPMS settings.

Fixed some Makefile problems with non-GL builds.

Fixed detection of MesaGL for version 3.3.

Better workaround to Red Hat 7.0's broken gcc.

Added Sparc Solaris kernel panic to bsod.

3.27

19-Jan-2001

New hacks: zoom and whirlwindwarp.

Fixed a free-memory-reference bug in sonar.

Better error handling when there are no suitable GL visuals.

Added diagnostic dialog when xscreensaver-demo is unable to launch
xscreensaver (e.g., when running as root.)

Fixed a bug that caused screenhack argument changes to be ignored
when xscreensaver-demo was running as root (if “root” and “nobody”
have different home directories.)

Made the programs default to “:0” if $DISPLAY is unset.

Made the -verbose output include information about which server
extensions were supported at compile time.

Worked around Red Hat 7.0's broken gcc 2.96.

Updated default delays on the GL hacks to look better on machines
with super-fast 3D hardware.

Install screensaver-properties-capplet to work around the usual
egregious GNOME lossage.

3.26

10-Nov-2000

Added “enabled” checkboxes in the list of hacks in xscreensaver-demo
(Gtk version only.)

New hacks hyperball, xrayswarm, and gflux.

New versions of nerverot, galaxy, and hypercube.

Small fixes to phosphor, shadebobs, xflame, and sonar.

Added external helper program xscreensaver-gl-helper to figure out
which X visual to use for OpenGL programs.

Configure updates for XFree86 4.0, and for BSD.

Made it be more tolerant of bogus /etc/group files.

When installing the PAM config file, first try to just copy an
existing “xdm” or “login” config file, so that xscreensaver does
authentication in the same way as the rest of the system.

Removed xscreensaver-demo's Ok and Cancel buttons, since they
were confusing people: all changes are now instantanious.

Made xscreensaver-demo install itself into the Gnome Control Center.

3.23

30-Jan-2000

Fixed some misplaced text fields in the Motif version of
xscreensaver-demo; fixed a crash in the Gtk version that would
happen if the programs list was empty.

Fixed a recently-introduced bug in pulsar.

Made sierpinski3d use solid tetrahedrons instead of points.

Added -trace option to xmatrix.

Added new hacks xteevee and xspirograph.

3.22

09-Dec-1999

Fixed some bugs in xscreensaver-demo.

Rewrote the Motif version of xscreensaver-demo to match the new Gtk
version.

The Athena toolkit is no longer supported.

3.21

18-Nov-1999

Tweaked the xscreensaver-demo UI (Gtk only.)

Fixed a few visual selection bugs. I think the proper GL visual
should be used with nVidia systems now.

Made the Makefiles obey $install_prefix.

Made the xscreensaver.spec file able to generate both GL and
non-GL packages simultaneously.

3.20

12-Nov-1999

Added new hacks ripples and sierpinski3d.

Made xscreensaver-command -exit be silent when no screen saver was
running (instead of complaining.)

Made webcollage and vidwhacker use xloadimage when available
(in addition to xli and xv.)

Improved memory usage in petri and gave it a hard cap on how much
memory it can allocate.

Added -watch option to xscreensaver-command.

Made xscreensaver-demo come up with the most-recently-run hack
selected by default.

Rewrote the Gtk version of xscreensaver-demo. It's a lot easier
to use now.

Extended the format of the programs list in the .xscreensaver file,
for the benefit of the new capabilities of xscreensaver-demo.
NOTE: you might want to delete your ~/.xscreensaver file and allow
it to be re-created! The old one should still work, but
xscreensaver-demo won't be as pretty.

3.19

30-Oct-1999

Fixed gcc dependencies in bumps and ccurve.

New hack, extrusion.

Some of the web sites that webcollage was using as its sources
changed formats; tweaked it to understand the current layouts.

Added typeahead in the password dialog: if the screen is locked, and
you unlock it by typing a character, that key will be automatically
inserted in the password dialog (unless it is Return, Enter, Space,
or a non-printing key like Shift.)

Made xmatrix take a -small option, since some folks with tiny
screens prefer a smaller font.

3.18

13-Oct-1999

New versions of shadebobs, lmorph, and distort.

Added ccurve, blaster, and bumps hacks.

Replaced forest hack with a rewritten version.

Worked around a Xinerama server bug.

Fixed a bug I introduced in 3.10 that caused some hacks to print out
superfluous warnings about not having gotten enough colors.

Made sproingies obey the -delay option.

Fixed a portability bug in shadebobs.

Made webcollage and vidwhacker use xli in preference to xv,
if it is available.

Added a new source of images to webcollage.

If running under KDE, xscreensaver will add itself to KDE's list of
screensavers (via xscreensaver.kss.)

Improved detection of GL libraries.

Made the password dialog include the date and time.

3.17

15-Jul-1999

New version of webcollage -- deals better with corrupted images,
and can use an http proxy.

New hack, xsublim (run it in the background, rather than adding it
to the programs list.)

The xscreensaver daemon was leaking a file descriptor each time you
edited your .xscreensaver file. Fixed.

3.16

23-Jun-1999

New version of shadebobs.

Improved image selection in webcollage, and sped it up slightly.

Made configure find the right version of perl.

Rewrote the CGI part of webcollage.

make clean was deleting some things it shouldn't.

Fixed a typo in the default programs list.

3.15

20-Jun-1999

Added webcollage and shadebobs hacks.

Added a -stdout arg to vidwhacker so that it can be used in a
pipeline.

Made petri use less memory.

3.14

11-Jun-1999

Various improvements to the Gtk port.

Turned off PAM by default on Solaris, since PAM seems generally to
be misconfigured out-of-the-box.

Made the --without-gtk configure option work.

Made configure check the Gtk version number, since it requires 1.2.

Fixed a bug in the code that attempted to prevent changes of screen
resolution while the screen is locked.

Fixed a race condition in xscreensaver-demo that could cause an X
error at startup.

Added -transparent option to deluxe.

Added petri hack.

3.13

31-May-1999

Ported xscreensaver-demo to Gtk.

Made it possible to build Motif, Gtk, and Athena versions of
xscreensaver-demo in the same directory without reconfiguring.

Made xscreensaver-demo chase symlinks before writing the
.xscreensaver file, so that if .xscreensaver is itself a symlink,
the underlying file will be replaced instead.

Some Makefile and configure tweaks for Solaris and FreeBSD.

Made it possible to set the fire color in xflame.

Made transparency work in TrueColor (for goop and qix.)

Fixed a multi-head bug introduced by the virtual viewports stuff.

3.12

10-May-1999

Made it so that you can't scroll the screen while the lock dialog is
up (with XFree86 virtual viewports.)

Fixed a bug in flag that caused bob's chin to get cut off after a
few iterations.

3.11

07-May-1999

Made xjack be black-on-white-ish, so that it looks less like a
computer screen and more like the typewritten paper it's supposed to
be.

New version of pulsar.

Fixed Solaris compilation problem in phosphor.

Made xscreensaver notice XFree86's virtual root window hack, so that
if the X server's root window is larger than the monitor's
displayable resolution, the screen saver will limit itself to the
area that actually appears on the screen.

Made the xscreensaver daemon do a better job of picking the visual
class that should be used for GL programs. Less user intervention
should be needed now: you can use the logical visual name GL
instead of having to figure out by hand which one to use.

Oops, the visual was defaulting to “best” instead of
“default”, because the .xscreensaver file was not being
loaded quite early enough.

Made configure figure out how to build icmp ping support into the
sonar hack automatically.

Made warnings about not being able to read shadow passwords not be
printed if compiled with PAM support.

Improved PAM startup diagnostics.

Worked around the Solaris PAM bug that was causing crashes there, so
now PAM is turned on by default.

Made configure detect the number of arguments that pam_strerror()
takes, since on Linux, this apparently changed between 2.0 and 2.2,
sigh.

Made the /proc/interrupts kludge look for “PS/2 Mouse” as well as
“keyboard”.

Made xscreensaver notice when there has been a sudden large jump in
wall-clock time, and if so, lock right away, instead of waiting for
“lockTimeout” to expire first. (Laptops need this for safer
recovery from “hibernation.”)

Added -throttle option to xscreensaver-command.

3.10

27-Apr-1999

Added phosphor, xmatrix, and pulsar hacks.

Fixed a bug in the color allocator that sometimes caused starfish
to fall back to monochrome.

Reduced the amount of code that runs before root privileges are
disavowed: “normal” and “shadow” passwords now do some
initialization as root, but the PAM and Kerberos authorization
schemes will be initialized while running as “nobody”. Supposedly
this closes a potential security hole when using Kerberos.

Generalized usage of the Double-Buffer server extension in several
hacks (compass, deluxe, interference, kumppa, and moire2.)

Fixed another visual-depth problem in rd-bomb.

The screen saver will now defer blanking if neither the keyboard nor
the mouse could be grabbed. Instead, it will just try again in a
few minutes. This fixes a bad interaction between xscreensaver and
programs like VMware that hold the mouse and keyboard grabbed for a
long time.

Added a new erase mode (expanding spiral.)

3.08

15-Mar-1999

Fixed some bugs in my port of t3d.

Added penetrate and deluxe hacks.

When linking against Motif 2.x, also link against XPM.

Added support for using /proc/interrupts for idle detection on
Linux. Now xscreensaver shouldn't kick in when the user is active
on a non-X virtual console.

Made flame ignore SIGFPE (not sure if this is the right fix; it
seems only to be needed on FreeBSD.)

Kludged rd-bomb work on visuals that are of depth 24 but that *do
not* support pixmaps of depth 32.

Fixed halo to work properly in TrueColor.

Changed xscreensaver.spec to install the hacks in
/usr/X11R6/lib/xscreensaver/ by default, since that's where recent
Red Hat distributions put them.

Added t3d hack.

Updated versions of crystal, hopalong, and flow from
xlockmore.

Imported demon and loop modes from xlockmore.

3.06

22-Nov-1998

Oops, the “default-n” visual descriptor was broken; it was always
installing a colormap if the installColormap preference was set,
meaning that xearth, xv and friends were using the wrong colors
on 8-bit systems.

Turned off HAVE_PING in sonar, since it compiles on some Linux
systems, but not others of similar vintage...

3.05

20-Nov-1998

Fixed an off-by-1 in distort.

Added sonar hack.

New version of glplanet (with stars.)

Made all hacks exit when you type q or ESC at them, and made
them obey the WM_DELETE_WINDOW ClientMessage.

Fixed a nonfatal buffer overrun in lament (note: lament still
doesn't work with MesaGL 3.0: it dies in
lambda_textured_triangle1(), which is Mesa's bug, not mine.)

3.04

16-Nov-1998

Added an xscreensaver.spec file, to make it easier for other folks
to generate RPMs.

Made the password code work on HPUX in the situation where:
“enhanced security” is available; but not used; but the user typed
a password more than 8 characters long anyway. FTSOHPUX.

3.03

15-Nov-1998

Made locking work when passwd aging is enabled.

Added support for PAM (Pluggable Authentication Modules.) It is
still turned off by default, though, since it doesn't seem to work
on Solaris 2.6, and has been behaving erratically on Red Hat 5.1.

Made each possible authentication method be tried in turn until one
succeeds; this means that Kerberos is being used, we will first
check Kerberos, and if that fails, will then consult the local
password file. Likewise with PAM.

Save and restore the bits under the passwd dialog, to avoid leaving
a black rectangle behind when unlocking is cancelled.

3.02

25-Oct-1998

Not everyone has sys/select.h, sigh...

3.01

24-Oct-1998

Some fixes to reflect.

Configure tweaks.

Made it log unsuccessful attempts to unlock the screen to syslog.

Fixed a bug where xscreensaver-demo could be seeing a different
programs list than xscreensaver did.

3.00

20-Oct-1998

The xscreensaver daemon no longer links against Motif or Athena:
demo-mode and the preferences panel are no longer built in to the
daemon, but are now handled by an external program,
xscreensaver-demo. (I decided that this, along with the recent
addition of the .xscreensaver config file, justified bumping the
version number to 3.00, since this is a fairly major architectural
change.)

Lines in the *programs resource may now begin with the character
“-”, meaning “don't run this hack.” In this way, it's possible to
disable a hack without throwing away the information about it
(making it easier to change your mind later.) Eventually the
preferences/demo mode GUI should represent this as a checkbox or
something.

Fixed a short race condition where it was possible for xscreensaver
to die with a BadWindow error if it was blanking the screen just as
another window was being deleted.

Made it possible to disable specific modes in bsod.

2.34

08-Oct-1998

Fixed a bug that was making pipes generate way too many valves.
Made the viewpoint in pipes be selected randomly instead of always
being -10 degrees.

Fixed a bug in the XSHM code, in the case where the server supports
the XSHM extension but is not the same machine as the client.

Made rd-bomb default to taking up the whole screen.

Made it not try to do fading/unfading if no PseudoColor visuals
exist.

Initial attempt at supporting VT-locking (doesn't work yet.)

Eliminated the captureStdout resource; now captureStderr
controls both streams.

Added -capture-stderr and -no-capture-stderr command-line
arguments.

Added glplanet hack.

When a hack is selected with xscreensaver-command -select, that
hack will be used until further notice (until the saver turns off,
or another activation command is issued.)

2.33

05-Oct-1998

Made xscreensaver-command print error messages: the xscreensaver
daemon now responds to ClientMessage events by writing a response
message on a window property, instead of just writing to its stderr.

Made the ~/.xscreensaver file be automatically reloaded when the
file date changes.

The password dialog and splash screen no longer depend on Motif or
Athena. This should clear up a number of focus problems, and is the
first step on the path toward moving all of the
Motif/Athena/whatever code out of the xscreensaver daemon, and into
external processes.

Don't complain about LessTif 0.86 any more, since the new password
dialog makes that problem go away.

Configure tweaks for Irix 6.5, SunOS 5.something.

New -reflect option to distort.

2.32

04-Oct-1998

Added reading and writing of a ~/.xscreensaver file, so that the
Preferences panel can save its settings.

New version of rubik.

Added -select N argument to xscreensaver-command.

Oops, left out some of the bubbles3d files...

2.31

02-Oct-1998

The cursor was invisible in the password dialog. Fixed.

Made configure warn against MesaGL 2.6.

Fixed X error at startup when using non-default visual.

New version of crystal, ant, and atlantis from xlockmore.

New hack, bubble3d.

Added some new modes to bsod.

2.30

23-Sep-1998

Changed the order in which -lSM and -lICE are linked to be after
Motif instead of before (Lesstif on Irix needs this.)

2.29

23-Sep-1998

Work around a bash bug in configure.

Tweaked HPUX paths again. FTSOHPUX.

Made configure recommend against LessTif 0.86, due to a bug in that
version that causes a security hole in the screen locking code.
LessTif 0.87 will fix it.

Made all of the --with options to configure accept a directory
option as well (so that --with-motif=/FOO will add -I/FOO/include
-L/FOO/lib). I believe this is the Configure Party Line of how do
to such things.

Fixed a bug where the mouse was left un-grabbed after the first time
the graphics hack was changed (simplified all of the mouse-grabbing
logic.)

Maybe possibly perhaps made vidwhacker really not leave stray xv
windows around. This time for sure.

Added a new erase mode (random dots fizzling out.)

Added -prefs argument to xscreensaver-command, that brings up
the Preferences dialog directly (it seems that nobody ever noticed
the Preferences button on the Demo Mode dialog, maybe this will
help.)

Added a splash screen. Turn it off with *splash:false.

2.28

21-Sep-1998

Better macsbug text in bsod.

New version of distort with many new modes.

Plugged a leak in coral.

Tweaked configure for HPUX.

Removed some compiler warnings.

More consistent usage of stderr versus stdout.

More diagnostics should an X error occur.

Fixed a possible crash in SGI-specific unfading code.

2.27

04-Aug-1998

Improved version of distort.

Made lament compile against OpenGL 1.0 (though it still requires
1.1 to work properly.)

Updated my email address and home page.

2.25

25-Jul-1998

Improved motion in rd-bomb.

Added XSHM (shared memory extension) support to the distort,
interference, moire, rd-bomb, and swirl hacks, which speeds
them up a bit.

Added lament hack.

2.24

30-Jun-1998

Tweaked the order of the -L options again.

Cleaned up configure's --help message.

Added kumppa hack.

Smarter maze-solving algorithm in maze.

Took xlyap out of the default list of hacks, since it's just
incredibly buggy (and slow.) Maybe someday someone will fix it...

Added distort hack, but didn't add it to the default list (yet)
because it's still too slow.

Made the Athena demo dialog look more like the Motif version; it has
a text-entry field now, too.

Made the Athena password dialog echo asterisks, like Motif does,
instead of using a flyspeck font.

Some random configure tweaks.

Added a timestamp resource that makes the -verbose messages
include the time at which they were printed.

2.23

21-Jun-1998

The fix for SGI's “scheme” nonsense broke things, and let the
user's “*background” resource show through. Fixed it in a different
way.

2.22

21-Jun-1998

Added support for the DPMS server extension (Display Power
Management System.)

Made configure advertize the --enable-subdir option a little more,
since that seemed to cause some people stress. Also, made that
directory be built into the xscreensaver executable, as a hardcoded
prefix to $PATH. (Might help, shouldn't hurt.)

Made configure prefer the two-arg gettimeofday to the one-arg
version, since AIX doesn't have any prototypes.

Made it work with Xaw3d (the 3D Athena library.)

Made make install create directories as necessary.

New version of lmorph from Sverre.

Added crystal and discreet hacks from xlockmore.

Added a new mode to bsod.

2.21

15-Jun-1998

Made xscreensaver-command -time use different words. (It now
describes the two states as “screen blanked since...” and “screen
non-blanked since...” instead of “active since...” and “inactive
since...” which a lot of people interpreted as meaning the opposite
of what was intended.)

Improved some error messages, in the hopes of making the distinction
between the xscreensaver and xscreensaver-command programs more
obvious.
